In a medieval college town in Italy, two young women, Meredith Kercher and Amanda Knox, arrived for a year abroad, seeking new horizons.

Six weeks later, Kercher returned home in a coffin and Knox became a global obsession.

Headline after headline labeled Knox a sexual thrill-seeker, a seductress and a murderer.

In an exclusive interview, Knox told ABC News' Diane Sawyer that while she'd heard the gist of the things circulated about her - "American temptress," "she-devil with an angel face," "heartless manipulator," "concertante of sex" and "sphinx of Perugia" - they were all wrong.

Amanda Knox's memoir, "Waiting to Be Heard," can be ordered HERE and HERE.

"I was in the courtroom when they were calling me 'devil,'" she said. "I mean, it's, it's one thing to be called certain things in the media and then it's another thing to be sitting in a courtroom, fighting for your life, while people are calling you a devil."

"For all intents and purposes, I was a murderer - whether I was or not," she said. "And I had to live with the idea that that would be my life."

She said everything she ever posted online, every boyfriend in her life, came back to haunt her. She told ABC News that she wanted the truth to come out.

"I'd like to be reconsidered as a person," Knox said. "What happened to me was surreal but it could've happened to anyone."

At times angry, other times guarded, in tears, Knox said that after six years of speculation, she is waiting to be heard.
